Great idea to determine amount of filament left on spool - maybe . . .

Recommended Posts

I'm sure something exists, but I have not been able to find a quick/easy way to determine the amount of filament left on a spool. How about making the spools with a series of holes along both side walls in identical positions. You put a rod through matching holes to determine how much is left on the spool. The approx amount remaining would be molded into the plastic. No scale or math needed.

Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
